Honing Machines: Ultra-Precision for Inner Hole Finishing

1. Introduction Different from grinders and lapping machines, honing machines achieve high-precision inner hole finishing through the combined motion of honing head rotation and reciprocation. They are essential for components requiring strict inner hole quality (roundness ≤ 0.001 mm, Ra ≤ 0.02 μm), such as engine cylinder bores, hydraulic valve holes, and bearing holes. 2....
